Abstract

The colour of red, purple, brown and white occurs in pericarp of rice. Here, the maize anthocyanin regulatory gene Lc under control of the promoter of the rice glutelin gene Gt1 was introduced in the white pericarp rice “Chao2-10” and purple pericarp rice “Qingjiaozidao”. The results demonstrated that some transgenic “Chao2-10” rice pericarps became brown, and the total flavonoid contents in the unpolished rice of the two transgenic rices increased significantly compared with their respective controls. Unpolished rice kernel thickness and weight in the two transgenic rices decreased slightly.
